BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to the rapid deployment and retrieval ofa frac water transfer system used in oil and gas operations, and moreparticularly, to the rapid deployment and retrieval of a frac watertransfer system used for hydraulic fracturing operations.

2. General Background

Hydraulic fracturing is a process used in the oil and gas industry tostimulate the production rate of a well. This process is also known as“fracing,” or conducting a “frac job,” in the industry. Techniques usedin hydraulic fracturing generally involve injecting a fluid down a wellat a high pressure. The injected fluid fractures the subterraneanformation surrounding the well. A proppant may also be added to thefluid to aid in propping the fractures. The fractures create channelsthrough which oil and/or gas can flow, facilitating the flow of the oiland/or gas to the well for production.

A typical preliminary step in preparing a frac job is transporting alarge volume of water (“frac water”) from a water source to a certaindestination. The destination may be any receptacle suitable for holdingfrac water located in the vicinity of where the frac job will be carriedout, including, but not limited to, a buffer pit, a frac pit, a fractank, or a work tank.

Water for use in hydraulic fracturing is often referred to as “fracwater”. Frac water may be obtained from one or more sources of watercomprising lakes, rivers, ponds, creeks, streams, well water, flow-backwater, produced water, treated water and any other source of water.Conventional methods of moving water over long distances involveextensive labor, time and transportation of, among other things,fixed-length pipes, fittings, and pumps.

One or more embodiments of the present invention relate to a system,method and apparatus for the rapid deployment and retrieval of a fracwater transfer system. Embodiments of the system and method of thepresent invention employ one or more flexible, lay flat hoses and/or oneor more segments of lay flat hose for the transfer of frac water overlong distances. In one embodiment, a computer program product isprovided.

The lay flat hose may be collapsible such that it may lay flat whensubstantially empty (i.e. substantially devoid of water or othermatter). Thus, the lay flat hose can be wound onto spools, folded intoflaking boxes, or otherwise stored in a compact manner. Because the hoseis very flexible and conforms to the terrain upon which it is laid, 90°,45°, 22.5°, or other elbow fittings would not be required in order tohave a pipeline containing turns. Characteristics of fluid flow in apipe such as working pressure, burst pressure, maximum efficiency rate,and maximum feasible rate are considerably higher and thus moredesirable for the lay flat hose than for pipes used in conventionalmethods for frac water transportation.

The lay flat hose may require fewer connections and pumps than the pipesused in conventional methods for frac water transportation to achievethe desired characteristics during frac water transfer. Moreover, thelay flat hose is difficult to damage, having a life expectancy ofapproximately five years, whereas the pipes used in conventional methodsfor frac water transportation have a life expectancy of approximately 2years.

In one conventional method, thirty foot (30′) long segments of aluminumpiping with an outer diameter often inches (10″) are connected in seriesto form a pipeline for transporting water over a long distance. A mileof straight piping (i.e., piping containing no turns) may requireapproximately 176 connections. Clamp type connections are typically usedto join the pipes. For pipelines containing turns, 90°, 45°, 22.5°, orother elbow fittings may be required. Water may potentially leak througheach connection or fitting, thereby decreasing the efficiency of thepipeline and wasting water. The working pressure of the aluminum pipingmay be approximately 80 psi and the burst pressure may be approximately150 psi. The maximum efficiency rate may be less than 50 bpm and themaximum feasible rate may be approximately 75 bpm.

In another conventional method, 3200 ft. or 500 ft. long segments ofpolyethylene piping with an outer diameter of 4 in. or 6 in.,respectively, are connected in series to form a pipeline fortransporting water over a long distance. Pipelines having thesespecifications transfer water at low rates and therefore may not beviable for real-time water transfer.

In yet another conventional method, 30 ft. long segments of polyethylenepiping with an outer diameter of 12 in. are connected in series to forma pipeline for transporting water over a long distance. A mile ofstraight piping may require approximately 176 connections. Water maypotentially leak through each connection, thereby decreasing theefficiency of the pipeline and wasting water. For pipelines containingturns, 90°, 45°, 22.5°, or other elbow fittings may be required. Theworking pressure of the polyethylene piping may be approximately 150 psiand the burst pressure may be approximately 317 psi.

The maximum efficiency rate may be approximately 76 bpm and the maximumfeasible rate may be approximately 92 bpm. Weighing approximately 26lbs/ft., manual handling of the polyethylene piping segments isimpractical. In one or more embodiments of the invention, a lay flathose may be deployed in segments ranging from about 5 ft. long to about700 ft. long and have a nominal inner diameter ranging from about 3 in.to about 16 in. In one or more embodiments, the lay flat hose isdeployed in 500 ft. long segments with a nominal inner diameter of 12in. A straight mile of pipeline constructed out of the lay flat hose mayrequire approximately 11 connections.

Because the hose is flexible and conforms to the terrain upon which itis laid, elbow fittings, which are prone to leaking, would not berequired for pipelines containing turns. The working pressure of the layflat hose may be approximately 175 psi and the burst pressure may beapproximately 400 psi. The maximum efficiency rate may be approximately100 bpm and the maximum feasible rate may be approximately 130 bpm. Thelay flat hose is made of circular woven high tenacity polyester. Anelastomeric polyurethane cover and lining completely encapsulate thepolyester. A variety of other types of lay flat hose may also beavailable at a range of sizes, materials, and capabilities. Any lay flathose suitable for the rapid deployment and retrieval of a frac watertransfer system may be used in embodiments of the present invention.

One or more embodiments of the invention are directed to a computerprogram product for use in connection with the design and deployment offrac water transfer systems in accordance with embodiments of theinvention. The computer program product may generate output data thatincludes measurements of frac water flow characteristics and/or pressurecharacteristics determined based on various input parameters. The outputdata generated by the computer program product may be utilized in makingdesign and equipment choice/placement decisions in connection with thedeployment of frac water transfer systems according to embodiments ofthe invention. The computer program product may comprise a computerusable medium having computer readable program code embodied therein.The computer readable program code may comprise computer readable codefor receiving as input one or more terrain parameters. The terrainparameters may include, but are not limited to, distances betweenadjacent discrete points along the flow path of the frac water from thesource to the destination as well as elevations at discrete points alongthe path. The discrete points between which distance measurements may betaken and/or the discrete points at which elevation measurements may betaken may coincide with the endpoints of segments of the flexible hose.Alternatively, the distance and elevation measurements may be takencontinuously at any one or more points along the path traversed by theflexible hose when deployed.

A manual survey of the terrain may be performed to determine thedistance and elevation parameters. Alternatively, or in conjunction withthe manual survey, a global positioning system (GPS) device may beemployed to precisely measure distances and elevation differencesbetween discrete points along the path. The GPS device may also be usedto take continuous distance and elevation measurements along the flowpath. In addition to the distance and elevation measurements, theterrain parameters may also comprise one or more parameters indicativeof a degree of obstruction at one or more discrete points along the pathof the flexible hose. More specifically, the one or more parametersindicative of a degree of obstruction may represent a measure of thedegree to which terrain characteristics may obstruct frac water flowthrough the flexible hose at one or more points along the flow path.

The distance, elevation, and obstruction parameters, along with anyother terrain parameters that may be determined, may together provide acomprehensive survey of the terrain. The computer readable program codemay further comprise computer readable program code for receiving asinput one or more design parameters. Design parameters may include anumber of and/or locations along the frac water flow path at which oneor more pumps and/or one or more filter pods may be placed. Adjustmentsto the number and/or placement of pumps and filter pods may affect fracwater flow rates and pressure and flow characteristics at various pointsalong the flow path.

The computer program product may take as inputs one or more of theterrain and/or design parameters noted above and generate output datarelating to one or more of the following pressure/flow characteristics:water hammer or hydraulic shock effects, wave velocity, friction,hydrostatic head, hydraulic force, pressure loss due to friction,positive pressure needed to overcome friction, or any combinationthereof.

However, it should be noted that the above list is not exhaustive andthe output data may include any other suitable measurement for assistingin the design, implementation, and deployment of a frac water transfersystem according to embodiments of the invention. In order to generatethe output data, the computer program product may also receive, asinput, data provided by various measurement devices disposed along thefrac water flow path correspondingly to the points between which and atwhich distance and elevation measurements are taken.

The output data may be provided in the form of a set of pressureprofiles reflecting any one or more of the measurements discussed abovetaken at discrete or continuous points along the frac water flow path.If the pressure and flow measurements provided by way of the pressureprofiles do not conform to desired values, one or more parameters may beadjusted and new output data based on the adjusted parameters may begenerated. This process may be performed iteratively until the desiredpressure and flow characteristics are achieved. More specifically, thepath of the flexible hose pipeline from source to destination as well asthe location and/or number of pumps and/or filter pods may be determinedthrough an assessment of the output data generated by the computerprogram product based on iterative adjustments to the input parameters.

DETAILED DESCRIPTION OF THE INVENTION

In one embodiment is provided a system 200 for rapidly deploying a fracwater transfer system, as depicted schematically in FIG. 2. The system200 comprises one or more segments of lay flat hose 304 wound onto oneor more spools or reels 202.

The spools 300 comprise a cylindrical core and two sidewalls having acircular cross section. In one or more embodiments, the sidewalls of thespools 300 may comprise spokes 302, as illustrated in FIGS. 24-28. Eachsidewall further comprises a circumferential surface.

The lay flat hose 304 may be manually wound onto the spools 202. The layflat hose 304 may comprise a first end 306 and a second end 312. Thesecond end 312 of the lay flat hose 304 is attached to the cylindricalcore or drum 308 of the spool 302 such that the end 312 will rotatealong with and at substantially the same rate as the drum 308 of thespool 300.

In various embodiments, each end 306, 312 of the lay flat hose segment304 comprises a coupling 310. While the coupling 310 of the second end312 may be disposed proximate the outer surface of the drum 308, and thelay flat hose 304 may be wound around both the drum 308 and the coupling310, such an arrangement may create an irregular shaped spoolingresembling an egg. To avoid the irregular shape, the coupling 310 of thesecond end 312 may be disposed within the drum 308 (see FIG. 28).Disposing the coupling 310 within the drum 308 further connects andanchors the second end 312 to the spool 300.

In one embodiment, a crank (not shown) that rotates the drum 308 of thespool 300 (or it may be turned manually), thereby rotating and windingthe lay flat hose 304 around the drum 308 of the spool 300. Manualadjustments in alignment of the lay flat hose 304 may be necessary toreduce tangling and ensure that the desired length of lay flat hose 304fits within the spool's 300 carrying capacity. The number of spools 300,300′, 300″, etc. necessary depends on the desired or required totallength of lay flat hose 304, which is determined, in part, by surveyingthe path from the water source 208 to the destination 210.

Reel Drive System

In various embodiments a drive system 502 may be used to facilitatewinding the segments of lay flat hose 304 onto the spools 300 duringtake up of lay flat hose 304. For example, drive system 502 may comprisea shaft fitted with friction rollers. The friction rollers may be spacedsuch that each friction roller aligns with and engages a circumferentialsurface of a sidewall of the spool 300. A power source in communicationwith a motor may rotate the shaft, and consequently rotate the frictionrollers, in one direction, causing the spool 300 to rotate in theopposite direction. The drive system may thus replace the manual cranksystem described above for winding the segments of lay flat hose 304onto the spools 300.

FIG. 19 is a perspective view of the reel rotating and tensioning system502. FIG. 20 is a perspective view of the reel rotating and tensioningsystem 502 shown from the opposite side as FIG. 19. FIG. 21 is aperspective view of the motor 511 powering the reel rotating andtensioning system 502. FIG. 22 is a perspective view of the motor 511powering the reel rotating and tensioning system taken from the oppositeside as FIG. 21. FIG. 23 is an exploded perspective view of the slidingconnection between the reel rotating and tensioning system of FIG. 21and the reel.

An axle drive subsystem 502 of the crawler 212 may comprise a driveshaft 504 that engages a connection 330 of the spool 300. The opposingend of the drive shaft 504 that does not engage the spool connection 330may be fitted with a second gear 510 (driven gear). The second gear's510 rotation correspondingly rotates the connection 330 and the spool300 in the same direction.

A first gear 508 (drive gear) may be substantially aligned in a parallelconfiguration with the second gear 510. A motor 511 may be used torotate the first gear 508. The teeth of the gears 508, 510 may mesh inorder to transmit the motor's torque. Alternatively, the second gear 510may be spaced apart from the first gear 508 and a chain 512 may be usedto transmit rotary motion from the first gear 508 to the second gear510. Guard 513 can cover gears 508, 510 and chain 512. Unlike themeshing configuration in which the gears 508, 510 rotate in oppositedirections, the drive chain transmits rotary motion such that the gears508, 510 rotate in the same direction. Because the second gear's 510rotation correspondingly rotates the spool 300 in the same direction,spool 300 rotates in the same direction as the second gear 510 and motor511. Rotation of spool 300 in one direction may lay lay flat hose 304,and rotation of spool 300 in the opposite direction may take up orretrieve lay flat hose 304.

A detachable connection can be made between reel 300 and axle drivesubsystem 502. FIG. 23 is an exploded perspective view of the slidingconnection 520 between the reel rotating and tensioning system 502 andthe reel 300. This slidable connection 520 can include first end 522 andsecond end 524 having first section 530 which accepts telescoping secondsection 540. Arrows 590 schematically indicate the ability of firstsection 530 to slide relative to second section 540, however, first andsecond sections are rotationally locked relative to each other so thatrotation of second section causes rotation of first section 530. Firstend 522 can be coupled to drive axle 504 of subsystem 502. Second end524 can be coupled to spool 300. Spool 300 can rotate relative to itssupport base 350. When connected by second end 524, rotation oftelescoping connection 520 causes rotation of spool 300 relative to base350.

Tensioning System for Hose Reel

A tensioning subsystem 602 is provided for the crawler 212 in accordancewith various embodiments of the invention. The tensioning subsystem 602may comprise a plurality of rollers 603, 604, 605 (see FIGS. 1-13 and47-50). The lay flat hose 304 may engage the rollers 603, 604, and 605in an alternating over-and-under configuration.

The second end 312 of the lay flat hose 304 may be connected to thespool 300 so that the lay flat hose may be retrieved. The axle drivesubsystem 502, described above with reference to FIG. 5, may rotate thespool 300 in either direction to retrieve and wind the lay flat hose 304onto the spool 300.

As the lay flat hose 304 passes through the rollers 603, 604, and 605 ofthe tensioning subsystem 602, rotational forces on reel 300 from axialshaft 506 cause tensile forces to act upon the lay flat hose 304,flattening the lay flat hose 304 and ensuring that it is neatly andtightly wound onto the spool 300. Further, because the tensioningsubsystem 602 flattens the lay flat hose 304, fluid is thereby squeezedout and removed from the lay flat hose 304. This water removing effectmay efficiently dry the lay flat hose 304 and allows it to be readilydeployed for further use or stored for later use. In variousembodiments, the rollers 603, 604, and 605 of the tensioning subsystem602 may be disposed towards the front of the crawler 212 to facilitateretrieval or take up of the lay flat hose 304 while the crawler 212 ismoving in a forward direction.

The rollers 603, 604, and 605 may be disposed at a height above theground sufficient to vertically lift the lay flat hose 304 off theground to reduce any wear and tear of the lay flat hose 304 that mayotherwise occur by its scraping against the ground during retrievalalong with also facilitating removal of water from the vertically liftedportion of the lay flat hose.

In various embodiments, the tensioning subsystem 602 may comprise oneroller 604 (see FIG. 40) or two rollers 603, 604.

The rollers 603, 604, and 605 may be closely spaced and have parallelaxes. The axes of the rollers 603, 604, and 605 may also be parallel tothe axis 301 of the spool 300. The rollers 603, 604, and 605 may bealigned laterally with respect to each other and the spool 300 suchthat, when the lay flat hose 304 is retrieved, the lay flat hose 304 ispulled longitudinally towards the spool 300 and wound onto the spool300.

Middle roller 604 may be pivotally connected to support structure 606.As shown in FIGS. 10-13, middle roller 604 can have a handle 609 tofacilitate selective pivoting of roller 604 relative to rollers 603 and605.

The first end 306 of the lay flat hose segment 304 is the end that isfirst unwound and offloaded from the spool 300 as the spool 300 isrotated by the axial drive subsystem 502. The second end 312 of the layflat hose 304 is the end that is last unwound and offloaded from thespool 300. The lay flat hose segment 304 may be manually positioned asit unwinds from the spool 300 to ensure placement of the lay flat hosesegment 304 suitable for connecting the first end 306 of the lay flathose segment to the second end 312 of the previously laid lay flat hosesegment 304.

In various embodiments, the spools 300 of lay flat hose 304 may beprovided with one or more support structures, frames, or “skids” 350.The skids 350 allow for a completely self-contained modular systemcomprising one or more spools 300 of lay flat hose 304. Each skid orframe or support 350 may further comprise one or more legs formaintaining the skids in a position suitable for facilitating theloading and offloading of the spools 300 onto and from the skids.Moreover, the legs may facilitate the loading and offloading of theskids 350 onto and from a vehicle or a trailer towed by a vehicle. Eachskid or frame or support 350 may further comprise a lifting mechanismallowing for the skid or frame to be self-supported.

Getting Reels to and/or from Stages Locations/Pre-Staging Reels forLayout or Take Up

The spools 300 (or combination of spool 300 and base 350) may bepre-staged at predetermined positions at which lay flat hose 304 will beneeded between the one or more water sources 208 and the one or moredestinations 210 to avoid deadheading. The pre-staging positions may bedetermined based on the terrain parameters gathered from the survey andthe output data of the computer program product 224.

The skids or frames 350 may be loaded onto one or more conveyancevehicles 204. Any type of conveyance vehicle 204 suitable for carryingskids or heavy equipment may be used, including, but not limited to: arollback trailer with a hydraulic lift, a flatbed trailer with aportable forklift, or a flatbed trailer with a knuckle-boom crane. Theskids or frames may be lifted and loaded onto the conveyance vehicle 204manually or with the aid of machinery suitable for lifting heavyequipment. For example, a forklift or a crane may be used to lift theskids onto the conveyance vehicle 204. In one or more embodiments of thepresent invention, the spools 300 may be loaded directly onto theconveyance vehicle 204 without the use of skids. It is to be understoodthat the present invention envisions the conveyance of modules ofmultiple spools 300 loaded onto skids and/or spools 300 without skids.The conveyance vehicle 204 onto which spools 300 are loaded may be a 48ft. flatbed trailer with the capacity to carry about 14 spools 300,approximately 1.25 ml. of lay flat hose 304. The use of a flatbedtrailer may comply with Department of Transportation (DOT) size andweight requirements. The use of a flatbed trailer as the conveyancevehicle 204 facilitates the use of a third party contractor for haulingof the load, which reduces the DOT risk exposure of the person or entityhiring the third party contractor. A desired number of spools 300 may beloaded onto the conveyance vehicle 204. The desired number of spools 300is determined, in part, based on the total length of lay flat hose 304needed to complete the designed pipeline 216 and on the conveyancevehicle's 204 carrying capacity.

The conveyance vehicle 204 may be driven from the equipment site 206 tothe water source 208 to begin laying the lay flat hose 304 towards thefrac water destination 210, i.e., the location to which water will betransported. The frac water destination 210 may be in the vicinity ofthe location where the frac job will be performed. Alternatively, theconveyance vehicle 204 may be driven to the destination 210, and the layflat hose 304 may be laid towards the water source 208. Besides spools300, the conveyance vehicle 204 may carry smaller off-road vehicles 212and/or various other types of equipment 214 that facilitate the rapiddeployment and retrieval of a frac water transfer system in accordancewith embodiments of the invention. One or more conveyance vehicles 204and/or off-road vehicles 212 may be used to transport additional spools300 of lay flat hose 304 or other equipment 214, if necessary, to thecurrent pipeline 216 work location.

The current pipeline 216 work location is defined herein as the vicinityof the location at which the last segment of lay flat hose 304 has beenlaid. The spools 300 may be offloaded from the conveyance vehicle 204 ina manner similar to that used in loading the skids onto the conveyancevehicle 204. However, a different manner of offloading the spools 300from the conveyance vehicle 204 may be used. For example, if a forkliftwas used to lift and load the spools 300 onto the conveyance vehicle204, a forklift may also be used to lift and offload the spools 300 fromthe conveyance vehicle 204. But the spools 300 may also be offloadedmanually or with the aid of any other machinery suitable for liftingheavy equipment.

In one or more embodiments, smaller off-road vehicles 212 (see FIGS.1-15) may be used to transport the spools 300 from the conveyancevehicle 204 to the current pipeline work location. The off-roadvehicle(s) 212 may be one or more all-terrain vehicles (ATVs), eachtowing a trailer capable of being towed in an all-terrain environment.The vehicles 212 may position the trailer proximate a spool such thatthe lifting mechanism on the vehicles 212 is capable of lifting andoffloading a spool 300 and lifting and loading the spool 300 onto thetrailer. A vehicle (or vehicles) 212 can be positioned near worklocation 216 as can be a trailer carrying spools 300.

Laying Out Hose from Vehicle

The segment of lay flat hose 304 to be laid may be unwound from thespool 300. The trailer on which the spool 300 is sitting may comprise afriction roller drive mechanism (not shown) for unwinding the lay flathose 304 from the spool 300. A shaft comprising mounted friction rollersmay be in contact with the circumferential surface of the sidewalls ofthe spool 300. A remote hydraulic power pack may provide the source ofpower to rotate the shaft, thus rotating the friction rollers in thesame direction. The friction rollers may comprise an outside contactsurface made of a material having a high coefficient of friction. Thecontact of the rotating friction rollers with the circumferentialsurfaces of the sidewalls of the spool 300 in turn causes the spool 300to rotate in the direction opposite of that in which the frictionrollers (and correspondingly, the shaft) are rotating. As the spool 300rotates, the lay flat hose 304 may be unwound and offloaded from thespool 300. In one or more embodiments, the drive mechanism may unwindthe lay flat hose 304 from the spools 300 at a rate ranging from about 1mph to about 4 mph.

FIG. 44 is a side view of vehicle 212 shown laying out hose 304 from areel 300. In this figure it is shown that hose 304 is being laid outfrom the rear or second end 1010 of vehicle 212. FIG. 45 is a rearperspective view of vehicle 212 taken from the non-driver side shownlaying out hose 304 from reel 300. FIG. 46 is a rear perspective view ofvehicle 212 taken from the driver side shown laying out hose from areel.

As section 314 of hose lays on the ground and vehicle 212 moves in thedirection of arrow 900 hose 304 is impart torsional forces on reel 300causing reel 300 to tend to rotate in the direction of arrow 920. Duringthis process drive axle subsystem 502 is coupled to reel 300, and motor511 can provide a braking action against free spinning of reel 300.Depending on the speed of vehicle 212 in the direction of arrow 900,operator can selectively control the rate of rotation of axle drivesubsystem 502 (and thereby reel 304) to prevent over-spinning of reel300 and allowing the flat laying of lay flat hose 304 in the directionof arrow 910.

Taking Up Previously Layed Out Hose

FIG. 47 is a front perspective view of vehicle 212 taken from thenon-driver side showing the taking up of hose 304 from the ground. FIG.48 is a side view of vehicle 212 showing the taking up of hose 304 fromthe ground. FIG. 49 is a front perspective view of vehicle 212 takenfrom the driver side showing the taking up of hose 304 from the ground.

As section 314 of hose is taken up from the ground and vehicle 212 movesin the direction of arrow 900 axle drive subsystem 502 imparts torsionalforces on reel 300 causing reel 300 to tend to rotate in the directionof arrow 940. During this process drive axle subsystem 502 is coupled toreel 300, and motor 511 can over-rotate reel 300 to maintain tension inhose 318 and assist in removal of water from section 317 of hose beingtaken up. Depending on the speed of vehicle 212 in the direction ofarrow 900, operator can selectively control the rate of rotation of axledrive subsystem 502 (and thereby reel 304) to maintain over rotation ofreel 300 and tension in hose section 318, and pick up hose section inthe direction of arrow 950 and allowing a dewatered and flat section oflay flat hose 304 to be wound onto reel 300.

During the take up process tensioning subsystem 602 comprising pluralityof rollers 603, 604, 605 engages lay flat hose 304 in an alternatingover-and-under configuration (arrows 690, 692, and 694 schematicallyindicate such over and under engagement). As the lay flat hose 304passes through the rollers 603, 604, and 605 of the tensioning subsystem602, rotational forces on reel 300 from axial shaft 506 cause tensileforces to act upon the lay flat hose 304, flattening the lay flat hose304 and ensuring that it is neatly and tightly wound onto the spool 300.Further, because the tensioning subsystem 602 flattens the lay flat hose304, fluid is thereby squeezed out and removed from the lay flat hose304. This water removing effect may efficiently dry the lay flat hose304 and allows it to be readily deployed for further use or stored forlater use. In various embodiments, the rollers 603, 604, and 605 of thetensioning subsystem 602 may be disposed towards the front of thecrawler 212 to facilitate retrieval or take up of the lay flat hose 304while the crawler 212 is moving in a forward direction.

The rollers 603, 604, and 605 may be disposed at a height above theground sufficient to vertically lift the lay flat hose 304 off theground to reduce any wear and tear of the lay flat hose 304 that mayotherwise occur by its scraping against the ground during retrievalalong with also facilitating removal of water from the vertically liftedportion of the lay flat hose.

As shown in FIGS. 49 and 50, middle roller 604 may be pivotallyconnected to support structure 606. As shown in FIGS. 10-13, middleroller 604 can have a handle 609 to facilitate selective pivoting ofroller 604 relative to rollers 603 and 605. Pivoting middle roller 604allows end coupling 310 to pass through tensioning system 602.

Vehicle 212 can provide an under carriage or trackedchassis 213 that enables the vehicle 212 to travel over the terrainwhere the pipeline 216 is to be placed. The vehicle 212 may have deck orbed 402, a lifting subsystem 404, a drive axle subsystem 502, and atensioning subsystem 602. The crawler 212 may be designed to be smallenough for maneuverability in tight spaces, but yet large enough tooptimize the number of trips required to deploy the lay flat hose 304and to optimize the time required to complete the trips.

In one or more embodiments, the crawler 212 may have a full lengthranging from about 12 ft. to about 15 ft., a full width ranging fromabout 5 ft. to about 7 ft., and a carrying capacity of over 7,000 lbs.Powered by an engine having between about 70 hp to about 80 hp or more,the crawler 212 may travel at a maximum speed ranging from about 4 mphto about 8 mph or higher. A driver-operator of the crawler 212 may beseated in a location relative to the bed or deck 402 such that the layflat hose 304 may be laid along the pipeline path 216 withoutobstructing the driver-operator's forward view. The bed 402 may bedesigned to provide a stable support structure for at least the spool300, the lay flat hose 304, and the spool's base 406.
